I'd reccomend going with a single X1900XTX instead and 2 gigs of OCZ memory on a DFI board with an Opteron 170 and then OC everything. Get a nice solid Lian-Li case with a 600w OCZ PSU. A nice 150gig 10,000RPM HD or two in RAID would be awesome.
You can choose the monitor, optical drive, keyboard and mouse.
Have fun ... lucky :-\
